Rev 8:12

“The sun, moon and stars represent the church, a third part of which is struck. This third is a designation, not a quantity. For there are two peoples within the church, that part of God, which is compared with the light, and that part of the devil, which is surrounded by the darkness of shadows, as the Scripture says, "I have compared your mother to the night." And this part was struck so that it might become apparent who is of God and who of the devil. It has been given over to its own sins and desires, so that their faults that have remained hidden and unknown to all might be revealed.”

“And a third of the sun was struck, and a third of the moon, etc. The beauty of the Church, like a shining star, is often obscured by false brethren, who make it shine less by their defection, whether in the prosperity or adversity of the world.”

“And a third part of the day did not shine, and likewise a third part of the night. Another Edition has it thus: And a third part of the day appeared, and likewise of the night. That is, it was struck so that a third part of the day and a third of the night might appear, which belong to Christ and which to the devil. I say, it was struck for this purpose, that, being handed over to their own wills, with sins overflowing and becoming insolent, it might be revealed in its time.”

“And the fourth angel sounded the trumpet, and the third part of the sun was smitten, and the third part of the moon, and the third part of the stars, so that the third part of them was darkened, and the day did not shine for a third part of it, and the night in like manner. By the sun, the moon, and the stars is symbolized the Church, and their darkness refers particularly to the perfidy of the heretics. Although two parts are made out of three thirds, namely one part belonging to the day with the sun, and another belonging to the night with the moon and the stars, the two nonetheless make one, or one is subdivided into two. He does this in order to indicate its overt error by the day, and its hidden error by the night, that is, respectively, the public conflicts of the heretics and their secret machinations. The reason why it is not said "the third part was smitten and darkened" but the third part was smitten so that it might be darkened (in due time), is that it is when they are openly separated from the Church that the heretics are truly darkened; for before that they are, as it were, hiddenly wounded. They are smitten out of the light of faith and the brightness of the divine Word. This destruction should not be ascribed to God, but understood in the same way as Pharaoh's heart being hardened. [Ex. 4:21; 7:3, 13, 22; 8:19; 9:12, 35; 10:1, 20, 27; 11:10; 14:4, 8]”

“'On this Caius said that, just as in the Flood the heavenly bodies were not taken away and suddenly submerged, thus also is it to be in the end, as it is written [St. Matth. xxiv. 37] ; and Paul says, When they shall say, Peace and safety, destruction shall come upon them [1 Thess. v. 3]. But Hippolytus says, in reply to this objection of the heretic: Before the Flood there was none of these signs, inasmuch as the Flood was partial; and the heavenly bodies were not removed, inasmuch as the general end had not arrived : but when heaven and earth are about to pass away [St. Matth. xxiv. 35], it must needs be that by little and little their splendour shall perish. And to this Joel testifies : Before him verily the earth shall be confounded and the heavens shaken, and the sun and moon shall be darkened, and the stars their light shall set [Joel ii. 10]. And our Lord said, in the Book of Luke, And there shall be signs in the sun and moon and stars, and on the earth distress of nations, and the powers which are in |401 heaven shall be shaken [St. Luke xxi. 25, 26]. And as to this, that He sent a manifest token, it is with regard to the non-perception of the unbelieving that He signifies. And as to the text, When they shall say Peace, destruction shall come upon them, it is with regard to the Jews that He signifies, that they expect to possess their land and to be able to live in peace, and forthwith Christ appears and they are put to shame.'”

“We have been taught by Joel the prophet that "the sun" will turn "into darkness, and the moon into blood before the coming of the day of the Lord, the great and glorious day." (Joel 2:31) This will happen when all these things take place. And Peter said in the second of his epistles: "The day of the Lord will come like a thief, during which the heavens will pass away with a loud noise, and the elements will be dissolved by fire." (2 Peter 3:10) But the Lord himself, according to Matthew (24:29), says that "immediately after the tribulation of those days, the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven." These things are now also taught through Revelation to occur at the end of the present age. But what does it mean that not all things on the earth, and in the sea and rivers, and also the elements in the heavens mentioned, will endure suffering, but only a third of them? This too is a precise demonstration of God's love for humanity, calling to repentance those people then living who are affected partially, not all the elements; and for those who do not turn back, it brings about total destruction thereafter. Such a thing the prophet also says: "he made a path by his anger, not sparing their souls from death." (Ps. 78:50) For the partial and gradual manifestation of God's wrath, as if proceeding along a road, is a door opened by repentance, calling people through the fear of what is happening to change their minds. But if this does not advance among them, he does not spare their souls from death.”
